How Laser Therapy Helps
The investigation of laser phototherapy as a potential modality to improve or effect nerve repair is building a body of research which demonstrates a favourable prognosis in the regeneration of peripheral nerves in both neurosensory and neuromotor deficits. Current nerve repair treatment focuses on trigeminal neuralgia, neuropathy, low back pain with sciatica, herpes zoster and Bell's Palsy.
Appropriate low level laser irradiation produces both local and systemic effects that have been shown to enhance the nerve regeneration process. It results in increased functional activity of the injured peripheral nerve, prevents or decreases degeneration in corresponding motor neurons of the spinal cord, and improves the axonal growth and myelinisation.
As a non-invasive and painless therapeutic treatment that can be used for almost any type of patient, including those who cannot use corticosteroids, such as diabetic and hypertensive patients, it has clear potential in this field.
"I was called out to a lady in her mid thirties with Bells Palsy - a temporary paralysis of the facial muscles involving the seventh cranial nerve. I used low level laser with an 820 cluster probe at a medium pulsing rate at 20 secs per point, over the painful paralysed areas. Within one day the symptoms had reduced significantly, and within 2 days there was virtually no trace of paralysis. This result was achieved with one treatment only."
Phototherapy in peripheral nerve regeneration: From basic science to clinical study
...Laser activation of nerve cells, their growth, and axonal sprouting can be considered as potential treatment of neuronal injury. Animal and clinical studies show the promoting action of phototherapy on peripheral nerve regeneration...
